Geosyntec, a global environmental engineering and consulting company, said Wednesday morning it has signed a deal to buy Las Vegas-based Department of Energy subcontractor Longenecker & Associates (L&A) for an undisclosed amount.
“This strategic acquisition accelerates Geosyntec’s growth in the federal sector, broadens service capabilities, and expands global market access for the combined organizations,” Florida-based Geosyntec said in the Dec. 17 news release.
The deal is expected to close later this year, according to the press release. No sales price was listed.
“L&A has built an exceptional reputation as a trusted partner to the U.S. federal government and the private sector, particularly in areas of national security, environmental remediation and clean energy,” Geosyntec President and CEO Majdi Othman, PhD, said in the release.
“This acquisition strengthens our ability to support complex energy and environmental challenges across the United States and internationally. I’m excited about what we can pursue together,” Othman said.
“When we began in the commercial nuclear power business 36 years ago, we offered solutions to regulatory and operating issues. Since that time, L&A has evolved to become one of the premier businesses supporting the vital national security, environmental, and energy missions of our clients,” L&A CEO John Longenecker said in the release.
“Combining our team with the outstanding strengths and capabilities of Geosyntec will allow us to expand and strengthen our ability to address the challenges of today and the future,” the Longenecker CEO said.
The release contained no details about Longenecker’s management following the acquisition. In addition to CEO John Longenecker and Founder/Board Chair Bonnie Longenecker, other top managers include L&A President Martin Schneider, a one-time editor of Exchange Monitor Publications, as well as Chief Operating Officer Christine Gelles.
In a Wednesday LinkedIn post, Schneider said he was “very excited for what’s ahead!”
Longenecker is a teaming subcontractor at BWXT-lead Hanford Tank Waste Operations & Closure’s (H2C) at the Hanford Site in Washington state.
Geosyntec is not entirely new to the DOE weapons complex. It is listed as a member of the Amentum-led Southern Ohio Cleanup, the team in charge of remediation at the Portsmouth Site in Piketon, Ohio.
Geosyntec has more than 2,600 engineers, scientists, and related technical and support people on staff, according to its website. The company provides services to markets including dams, data services, and electric power utilities, according to its website.
Merger activity among DOE nuclear contractors has been slow during 2025, unlike 2024 which saw completion of an Amentum-Jacobs government contracting deal as well as Bernhard Capital Partners purchase of Strategic Management Solutions and other small companies.
